In 1992, the album Hollywood Town Hall launched the career of the Minnesota band The Jayhawks, making it a seminal force in the burgeoning sound known as alt-country. Co-founders Mark Olson and Gary Louris found their harmonies and their songwriting styles fit together like few others, and The Jayhawks toured relentlessly — so much so that it took them three years to follow up that hit album with a new one.
